“…Four different PIBSA samples were collected after respectively 4, 7, 10 and 14 h of reaction between PIB and MAH in large excess. All PIBSA were purified from the unreacted MAH (stripping at reduced pressure) and the conversion of PIB to PIBSA was evaluated by FTIR monitoring the disappearance of the vinylidene peak of PIB centered at 890 cm −1 and the emersion of the grafted SA band respectively due to the symmetric carbonyl stretching at 1 855 cm −1 and the asymmetric one pointed at 1 788 cm −1 3…”

“…The functionalization reaction provided, after 10 h, PIBSA derivatives with SA content per reacted PIB higher than 2. Differently from potentiometric titration procedure, NMR investigation was able to discriminate the SA grafted at end α ‐olefin PIB groups from those grafted at internal β ‐olefin units 3, 4, 14, 15. This allowed, for example, the quantification of PIBSA (c) and PIBSA (d) molar content during the functionalization reaction (Table 2).…”

“…PIBSI is prepared by treating suitable amines (e.g., alkylene PAMs) with PIBSA at temperatures below 200 °C. The latter are generally prepared by the reaction between highly reactive PIB and maleic anhydride (MAH), according to the thermal induced Alder‐Ene mechanism 3…”

PIB derivatives such as PIBSAs and the corresponding PIBSIs characterized by different contents of functional groups were prepared. They showed luminescence both in their neat form and in heptane solution when the amount of functional groups per polymer chain was higher than a critical value. This behavior is attributed to aggregation-induced emission, a phenomenon caused by the aggregation of non-emissive chromophoric carbonyl groups present on PIB derivatives. AIE was studied in heptane solution as a function of the type (SAs or succinimides) and number of interacting functional groups. The results suggest that fluorescence measurements might be an effective tool to determine the degree of functionalization of PIB derivative

Representative Polyisobutylene succinic anhydride (PIBSA) samples have been studied by different MS techniques including Electrospray Ionization Fourier Transform Ion Cyclotron Resonance MS (ESI‐FTMS) (positive and negative modes), Atmospheric Pressure Chemical Ionization Fourier Transform Ion Cyclotron Resonance MS (negative mode), and Matrix‐Assisted Laser Desorption/Ionization Time‐of‐Flight (positive and negative modes). Negative ion ESI‐FTMS produces the best results. Differences between “mono‐succan” and “di‐succan” content can readily be observed. The source of the PIBSA (PIBSA‐I and PIBSA‐II processes) can be easily distinguished and the formation of methyl esters and amide derivatives can provide complementary data. The experiments have demonstrated the capabilities of mass spectrometry to detect and characterize such polymers samples. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

In the present work, the preparation of different styrene-based polymer films containing small amounts of TPE and the evaluation of their photoluminescent behaviour is reported. When TPE is dispersed in a poor solvent or in a glassy PS matrix, the arrested intramolecular rotations of its aryls favour the strong emission of light centred at about 455-460 nm. Conversely, TPE fluorescence significantly weakens to a faint signal when good solvents or viscous but not glassy polymer matrices are used. Near-field optical microscopy correlates the fluorescence behaviour with the different matrix morphologies. These results should be able to be used for developing a new tool for polymer traceability
